Abstract: 5661. Symons, E. B. March 7. Disk mills; roller-and-ring mills.-A crushing- machine comprises two opposed dish-shaped crushing-members J<1>, K, Fig. 1, rotating in the same direction at an angle to each other and mounted on shafts A, B arranged one within the other, means being provided for varying the distance between the members independently of their inclination to each other. The shaft B has a spherical enlargement B' at one end adapted to engage an antifriction lining A<6> on the inside of an enlargement or flange A' at the end of the hollow shaft A. A sleeve B<2> at the other end of the shaft B bears at one end against the spherical end A<7> of the shaft A and at the other end is engaged by nuts B<3>, B<4>. The sleeve B<2> is carried in a bearing F, Fig. 4, mounted upon trunnions F<1> in lugs F<2> upon U-shaped members F<3> which have flanges F<4> seated upon the bosses F<5> of a disk F<6>. By means of screws G engaging lugs G<3> on the disk F<6> the end of the shaft B can be raised or lowered. The crusbing-plate J<1> is secured to the piece B<1> by a screw J<2> which is locked by a spring-pressed collar J<4> having teeth engaging teeth J<8> on the screw. A small screw in the screw J<3> is adapted to engage a lug on the collar and disengage the parts. The crushing-plate K is secured by angular bolts K' to a piece A' carried by a collar A<3> screwed on the flange A'. The shaft A is held against lateral displacement in the bearing-sleeves C by collars C', and is driven by a pulley C<3>. The bearing-surfaces in the sleeves C consist of antifriction metal segments D, Fig. 2, with their longitudinal sides at an angle one with the other. The segments abut at one end upon a shoulder D' and are held in place by a spring ring D' engaging a groove D<3> in the body of the sleeve. The collars E surrounding the shaft A at the ends of the bearings are secured by screws and provided with inclined blades E<3>. Rings.E' having L-sbaped channels E<5> surround the shaft and are held against the sleeves C by screws E<6>. A pump L driven by a belt L<1> from the shaft A forces oil from a reservoir L' through pipes L<3> to openings L<4> in the bearing-sleeves C. The oil works out along the shaft A and is caught by the vanes on the collars E and thrown outwards into the openings E<5>, whence it returns by pipes L<3> to the reservoir. Oil supplied to the bearing F by a cup O passes out into an annular channel B<5> in the sleeve B<2> and then through openings B<6> to the surface B<7>. The parts A', B' are lubricated by oil passing from a cup P through piping P<3> to passages P<4>, P<5> in the shaft B. A water tank M is connected at the top and bottom by pipes M<1>, M<3> to the top and bottom of a chamber M<2> in the bearing C. The ring H is held between the flanges H<2>, H<3> by means of bolts, and the feed-shoot H<7> enters an opening in the hood H<6> which forms a continuation of the flange H<2>. In a modification, the material broken by the plates is pulverized by rollers Q<3>, Figs. 9 and 10, travelling upon a ring H. The rollers are located between flanges Q, Q<1> on the plate A' and collar A<3>, and the bearings Q<5> of the shafts of the rollers are connected by arms Q<6> to bearings Q<7> upon shafts Q<8>. The slots in the flanges Q, Q' which permit the rolls to move radially, are covered by annular rings R', and the flanges H<2>, H<3> which support the ring H are provided with discharge openings at either side. The ring H may be curved in crosssection and the rollers shaped to correspond.
